Abstract:

The testing and verification of airborne software is an important method to ensure the correctness and reliability of airborne software. Software testing and verification are inseparable from the support of tools. The use of tools can improve efficiency and reduce costs. Research on testing and verification tools for airborne software is a guarantee for adequate testing and verification. Firstly, it introduces the airborne software and airworthiness standards. Secondly, in accordance with the series of airworthiness standards, the functions, characteristics, and characteristics of the tools are analyzed from the perspectives of DO-178C, model-based development and verification（DO-331）, formal methods（DO-333）. The application is introduced in detail, and its development status is summarized. Finally, the problems in the testing and verification of airborne embedded software and the development of tools are summarized and the trends are analyzed.

Key words: airborne software testing and verification tools, airworthiness standards, DO-178C, model-based, formal methods
